Last week we started to notice one of our girls was having problems seeing. We would wave greens in front of her when we are feeding them to the girls and she wouldn't see it. She would just kind of stand there facing a wall. She appears to see shadows, but not very clearly. We have separated her for now, she appears to be healthy and is eating. Her pooh seems good. When we let her out in the garden with us she just follows our voice or shadow. Has anybody ever seen this? We don't want to put her back with the other ones until we know it is not contagious. Everyone else seems fine. If it isn't something contagious, we plan to have her hang out with one of her sisters for a while so they can form a bond and them reintroduce her under careful watch (the rooster was picking on her). Any other suggestions? Thanks!
